Hi,

 

A while back, I asked a question about defragging a SSD. I was told that I should not try to use the Windows Defrag tool because a SSD could be damaged by it because of the architecture of the SSDs internal workings.

 

This leads me to ask about using a program like Eraser which erases files, or an entire disk, by overwriting the data tracks several times. But since the SSD doesn't have tracks, I'm wondering if a Program like Eraser will work on the SSD or might even cause problems.

 

Is just deleting a file sufficient to make it inaccessible to someone trying to re-access the file in the future? And what about trying to retrieve a file that was deleted accidentally? In other words, when a file is deleted from a SSD, is it really gone forever?

If TRIM is enabled on the SSD, the files are deleted permanently.

Defragging doesn't damage the SSD but it can shorten it's life because of the writes which a SSD only has a certain amount of. By erasing the SSD you are writing to the drive and in the process shortening it's life but it will not damage it.

Hello Warthog-Fan,

 

I did some research on this very issue some time ago.  Note that defragging an SSD doesn't make any sense as an SSD functions very differently from a hard-drive.

 

Rather than overwriting the drive, the drive is purged, generally with an electrical pulse of some sort.  For more complete information, please read the 2nd half of this article: http://www.zdnet.com/article/how-to-securely-erase-hard-drives-hdds-and-solid-state-drives-ssds/ and also here: https://www.kingston.com/us/community/articledetail?ArticleId=10
